We are being asked to determine the number of protons and neutrons present in each nucleus and the number of electrons present in each ion
An element can be represented as:
You can determine the identity of the element using its atomic number:
Atomic number (Z):
• represents the identity of the element
• reveals the number of protons
• in a neutral element:
# of protons = # of electrons
Mass number (A)
• reveals the number of protons and neutrons
mass number = # of protons + # of neutrons
We will do the following steps
Step 1: Determine the number of protons
Step 2: Determine the number of neutrons
Step 3: Determine the number of electrons
Four Fe2+ ions are key components of hemoglobin, the protein that transports oxygen in the blood. Assuming that these ions are 53Fe2+, how many protons and neutrons are present in each nucleus, and how many electrons are present in each ion?
